Specially formulated mixture of carbonates, sulfates, and chlorides of sodium, magnesium, calcium and potassium with all necessary minor and trace minerals to approximate Rift Lake water chemistry. Designed to provide natural water chemistry to African cichlids and other rift lake fishes without significantly raising pH. Compatible with and designed for use with A F Cichlid Buffer for pH control and A F Cichlid Rift Lake Trace Elements. Contains no phosphates, nitrates, silicates or organics to pollute the system. (Note: competing products usually contain very high levels of silicates which encourage diatom (algae) growth on the tank walls This product does not) A F Cichlid Chemistry will also benefit most American cichlids whose waters are hard and have high pH's above 7.8. First read the considerations for use section below. Use 1 to 4 teaspoons (6 to 24 grams) of A F Cichlid Chemistry per 10 gallons (38 l) for initial tank setup or for water changes, depending on initial hardness and desired value. Next use A F Cichlid Buffer to adjust pH and alkalinity to the proper value.

For best results, start with water prepared by reverse osmosis. If using tap water, dechlorinate and measure TDS (total dissolved solids) or GH (general hardness). Using this product, adjust water hardness to the desired value for the type of fish you are keeping. A good rule of thumb, dissolve in water 1 to 4 teaspoons (6 to 24 grams) of KENT Marine Cichlid Chemistry in a separate clean container. Add this to each 10 gallons of aquarium water at initial tank setup or when performing water changes. When replacing water due to evaporation use plain R/O water or dechlorinated tap water (no Cichlid Chemistry added) as dissolved solids do not evaporate.
